- vTo all whom z'may concern:

P1 Be it known that I, JOHN JosErirDUKE'r,

acitizen` of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Oil-Burners; and I d declare the following to be a full, clear, and

. `exact description ofthe invention, such as yWill enable others skilled inthe art to which it appertains to make and use the same, reference being had to the accompanying drawings,` and to the letters and figures of referl `ence marked thereon, which forni a part of thislspecifieation. Y

My invention relates to a generator and burner for utilizing' heavy fuel oils Afor heat- 1 ing and for cookingyand its object is to pro a vide a device which shall be simple, safeand 'i elieient and, more particularly, to provide a gas generator Withan outlet which shall be self cleanin and proof against the accunnr,

lation of ad lering carbon and sediment; to

. provide `such device with a generator which -Inay be readily cleaned and which inay be easily reino-ved or installed; to providean i arrangement of the parts whereby single generator and air-mixing chamber are adapted to supply gas mixed with an'to `either or any or all of a plurality of burners,

each of suoli burnersl being controlled by means of a separate valve; to provide an improved arrangement ot parts whereby each of the burners of my device maybe independently adjusted to the most efficient location for ilse in the ordinary cooking or heating stove; to furnish a construction by means of which should any unconverted oil escape through the generator it will flow into the air-.inlet pipe and thence out into a safe receptacle, while,A at: the 'saine time, should any gas escape through lthis drain the will mingle with the infiowing air 1 l and will becarried to the air-mixing,r cham- -ber and thence y to the burner or burners.

The invention is fully described in the following specification, and While it is capable of embodiment in numerous forms, a.

preferred embodiment thereof is illustrated `in the accompanying drawings, inY Which--d Figurel is a top plan/-view'of my device; Fig. "2, a front elevation of the same; Fig. 3, a transverse, sectional elevation of'a pon tion of the same taken on line rfc-a3 Figs. 1 and 2; Fig. el, a central longitudinal see tional elevation of the generator hereinafter' referred to., together With its controlling menu- .epeeiication of Letters Patent.

valves and supports; Fig. 5,' a central hori- AZontal sectional plan-view of the valve piece generator hereinafter referred to, on an enlarged scale, and Eig. 8, ay side-view of the valve-stern supporting bracket 28 hereinafter referred to, detache Like letters and numerals of reference indicate like parts throughout the drawings.

In the drawings, 1 is a supply pipe and duct leading from a pressure tankf-not sliou"n,-to thelinletof a generatortube i2 through an oil supply valve 3; et .is a valvestem having a handle This valves-teni carries a valve G Iadapted t0 seat as at G to control the flow of-gas or oil fronigthe generator-tube. Projecting forwardlyfrom the v-alved end lof the generator is a needle like portion 7 which extends into and through a sharp edgedorifice 8 which` leads from the surrounding chamber 9. 'This chamber designed to ycatch particles of carbon or sediment which might clog the orifice 8. grooved as an additional means for preventing the closing of the orifice 8. Around the stem Je in the generator-tube isivouud spirally a wire 10 for breaking up the oil and for retarding its How and prolonging: its cxposuredtov the heat of the tube and coil in a subdivided condition. The aperture leads into an air-supply pipe 11 which opens into a mixing chamber 12 leading into a ilvc-chainber, the casing of which is desi nated at 13. (See Figs. 1 and In this valve-chamber, 14, 'are located four valved outlets, viz., 15, 16, 17 and 18. Valve l5 controls a passage 19 connected as at 20, with a burnerl for heating the generator and ylocated immediately beneath and parallel with the generator-tube 2. Valve 16 controls a passage through theswinging arm 22 leading to the burner 23. Valve 17 controis a passage through swinging' armlr` The needle 7 is longitudinally these tour valve-stems arel supported and held in proper alinement by the bracket member 28 (see Fig'. 8,) having dowm Wardly projecting `arms provided with ap- .rtures 15", 16", 17b and 18", which apertures receive and support the corresponding valve-stem ends. The piece 28 has at one edge a jaw 29 which receives one end of the generator-tube .as well as the piece 30 represented in plan view in Fig. 5. The upper jaw member ot' the a-w 29 carries a set screw 29 and the lower jaw member has a socket 29 which receives a lug 30 on the piece 30. The oil inlet-duct l controlled by valve 3, (see Fig. 4), is in communication with the oil-inlet of the generator tube, and when the- Setscrew 29 is set. up a tightjoint is established between these two portions ot' the oil duct. In communication with the oil duct 1 :in the piece 30 is an oil duct 31, controlled by avalve which duct leads to and discharges into the oil-pan 325 provided to re ceive oil for preheating the generator. An extension 34 from the oil-pan passes through and is secured in hole 35 in the piece Q8 and supports in operative position the bracket member QS and its connected parts.

Leading from the mixing chamber 12 is a down pipe 36 which at its lower end is connected with the air inlet pipe 11, the arrangement being such that in case there is an overflow ot oil from the generator-tuln` into the air mixing pipe, it will flow down into the air-inlet pipe and thence into a suit able receptacle-not shown. In case nneonsinned gas or vapor is carried into the downpipe 36 it will mingle with the ascending air and pass into the. mixing chamber.

'lhe arms 22 and 24 which carry the burners 23 and 25 are swiveled at their inner ends, as at 22 and Qtftupon the top ot' the valve easing 13. These arms are hollow aml they provide passages which at their inner ends are in communication with their appropriate gasoutlets in the valve-chamber l-l. as above described. and at theireuter ends are in connnunication with the chambers oi' the burners Il and 25. 'lhese burners are hollow rings, radially keri'ed on their upper sides, andare swiveled at one side upon their respective arms. as illustrated in Figs. l and 3. rl`l1is arrangement ol` the swinging arms and ol! the swinging lnnner-rings permits a wide adjustment ol' the burners in every direction horizontally` so that the burners may be placed to aecoinnualate the stove-holes ot' any cooking stove. or range with which my device may be asstw-iated.

'lhe oven burner consists of an elongated hollow casting having a hollow' lug which is pivoted upon they side ot the valve. casing lil as clearly illustrated in ltig. l. 'lhe chamber ol` the burner 2T is in eonununieation with the gas chamber 11i through passage QG controlled by the valve 18 as above point ed out. The oven burner Q7 may be tilted to such position as will prove most etlicient in relation to the' front wall of the bake oven of an ordinary cook'gstoife and may be rigidly secured in such adjusted position by means of screw bolt 27a' which also 'serves asia pivot pin. l W

37`37 are stout bolts which are screwed into the under side of the device and which form vertically adjustable legs which support the burners and generating apparatus in horizontal position at such height as'wmay.

Ibe desired.

The operation of my device is as follows: To start the ap )a atus the valve 32 is opened to supply a Asu cient" quantity of oil to the" generator pan 33 which is supplied with a suitable wick. lVhen the generator-tube '2 which lies in the flame from the pan becomes sufficiently heated. the valve 5 is opened permitting the oil to flow into the generator-tube. In its slow passage through the tube in contact with the 'alls of thc tube and the hot coiled Wire the oil is vaporized and turned to a gas which discharges through the valve 6 and the orifice 7 and iningles with the air supply. lhe mixture is conducted to the valve chamber 14: by the pipe 12 and is thence distributed through the several valves heretofore.referred to in the manner de scribed. The oil in theA pan 33 being consumed. the valve 32 is closed and the valve 15 is opened and gas is now supplied to the burner :'21 which continues to supply a tlame to the. generator-tube aslong as the supply of gas is continued. It will be seen that the supply ot fuel oil may be regulated asmay be desired and that Veither or anyl or all ot the burners may be used as may be desired.

Having described my invention. what I claim and desire to secure by Letters Patent. is-
